Any of you guys EVER seen this?

Aftermarket fused rollers were the worst.

No matter which brand, they ALL sucked, big time.

I haven't seen that in years. I think the last time I saw that was on the rollers between the fuser and sorter on Canon NP6085s. But those rollers were close to ten years old then, and if you didn't catch them in time the rubber part of the roller would assume the viscosity of pudding.
That's also weird as when the Riso GRs came out with feed tires that were the same blue color they were harder than anything we had ever seen before.

I had this sep roller and to the best of my knowledge it was OEM. Since we use vendor branding and in parts manuals the numbers were different, so I can't back track, but this for sure was on hard roller and I ditched it as it would wear out the orange feed roller twice as fast and still causing no feed jams. I wonder if the torque limiter was actually the problem, as it seems to me that this roller definitely suffered from it.
Have had these flats on C550 when the LCT tray 3,4 main drive was causing intermittent jamming.
Or weak sep. roller spring in the bracket. Not enough force to turn the sep. roller so it just slides the paper along and gives it a shave.

Just checked that picture enlarged and that looks like the roller has been bullied by the feds.... Hahaha
Sucks that you have to change the lot .. Again!
Might be wise make couple beforehand and just swap it on flight.

Ha! we were cleaning out old desk drawers in the shop awhile back, found a set of those.. Initially I asked our Riso guru what they were for, he basically said they were useless..

Torque limiters will do that.

I looked at that again and realized it looks like there's tread on the dent. Did you replace them? Looks like a manufacturer defect. Or maybe I've had too much to drink and I should just go to bed. This reply took 1/2 hour to typoe.

The indentation has not be "shaved" but is pushed in. The original profile of the roller is still visible. The cassette #2 where this has been installed was not in use for three weeks cause customer uses this tray only for A3.

Thank God you replaced it only 2 weeks ago, think three would make it to the shaft.

I've noticed, thats why I added the bullying note (joke) with federal agents " Feds" after my initial post

I saw that 2 weeks ago. Not as bad, but it was the first time I had seen an indent on a roller made of that material. It was the reverse roller in the adf of a c652 with a fairly low meter. Customer kept reporting adf issues, jamming and pulling extra pages, but the meter count did not justify new rubber. The environment was very dusty and I was going at it from that angle. Finally with nothing else to try, I pulled the roller and saw my reason for jamming. Mine was an OEM roller.
